1) Participant background data: 'AntisaccEEG_background.xls/txt'
Principal components were extracted using SPSS 17.0.

2) Behavioral data: 'AntisaccEEG_behavioral.txt'

3a) EEG target-locked and saccade-locked data
Issued with Brain Vision Analyzer 2.1.0 (Brain Products) and EEGLAB toolbox (version 13.2.2) for MATLAB (version 7.12.0, R2011a).
Files (pairs of ".set" and ".fdt" files need to be loaded together) contain cleaned, segmented but unaveraged and non baseline-corrected data per participant and condition.
Data are organised as target-locked (-300 ms cue-locked, 0 ms target-locked) and saccade-locked. Baselines for target-locked segments: -400 to -300 ms which corresponds to the time window 100-0 ms before cue onset; baseline for saccade locked segments: -700 to -600 ms corresponding to a time window during fixation before cue onset.
These files were used for creating ERP figures and for conducting ERSP (event-related spectral perturbation; time-frequency analysis) and DCM (dynamic causal modelling) analyses.

File names:
B01...: bilingual participant 01
M01...: monolingual participant 01

Conditions:
A: Antisaccades
P: Prosaccades
AA: Antisaccades preceded by Antisaccades
PA: Antisaccades preceded by Prosaccades
PP: Prosaccades preceded by Prosaccades
AP: Prosaccades preceded by Antisaccades
m_: mixed task blocks
b_: single task blocks
_target: target-locked (-300 ms cue-locked, 0 ms target-locked)
_sacc: saccade-locked

In EEGLAB, two 'studies' were created, for target- and saccade-locked segments respectively: 'study_mAvsP_target.study', 'study_mAvsP_sacc.study'.
Each study contains two designs. For each involved participant dataset, the respective design files are given ('design1...', 'design2...') for ERPs and ERSPs.
Design1 allows for studying the factors 'Condition' and 'Group' and their interaction in ERP and ERSP data.
Design2 allows for studying the factor 'Condition' in ERP and ERSP data.

3b) ERP_timewindows (files tagged "Data" & "ERP_timewindow") 
Issued with Brain Vision Analyzer 2.1.0 (Brain Products) 
Mean amplitude values for each time window of interest are given.

3c) DCM data (files tagged "Data" & "DCM")
Issued with SPM12 (Wellcome Trust Centre for Neuroimaging, London, UK).
Individual files ('DCM...') as well as a synthetic file including the extracted values for modulatory connections ('DCM_modulatory_connections.mat', see also 'AntisaccEEG_DCM_modulatory_connections.txt') are given.

3e) Correlation analyses: 'AntisaccEEG_correlation_data.txt'
The file contains the effect sizes of interest and the linguistic background factors used for correlation analyses.
